This paper describes a new process for the production of Na

123

I radiopharmaceutical through

121

Sb (α

2n)

123

I reaction. Target of natural antimony was electroplated in a HF bath on a silver-copper complex plate. The antinomy layer thus obtained was firmly bound and evenly distributed with definite thickness and good thermal conductivity. The targets were irradiated by α particles of ~ 30MeV to produce

123

I which transformed directly into pure Na

123

I radiopharmaceutical through a quick dry process of high efficiency. The total time of processing was within an hour. The overall radiochemical yield was over 98% with radionuclidic purity over 98.5%

radiochemical purity over 98%

chemical impurities of Cu and Sb all less than 1ppm. The thick target yield was around 0.3mCi/μAh. The product proved good in preclinical tests for injection

in-vivo uses and labelling of organic radiopharmaceuticals.
